Lewis G Rosenthal inspired by my mods has been applying reading up my notes and doing some modding on his own. He's sent me a bunch of modded extensions which I'm slowly going through and posting to my xSidebar site including:

Flexible Identity 0.5.8 (Thunderbird)Lewis managed to get Paul Kolomiets to add SeaMonkey compatibility to Flexible Identity so now you can get it directly from:https://addons.mozilla.org/addon/295715/

I would like to see FEBE added to the list of Firefox extensions that SeaMonkey can also use. For backup, where you do not want the entire profile, but an installer for all your chosen extensions, FEBE is a good app.

Message Archive Options lets you set the format of the dates used for the year and month folders that the Archive function in Thunderbird3 creates. It exposes the (hidden) preference that lets you change the granularity of the folders to either a single folder; an archive folder and a year subfolder; or a month also.

Additionally the addon can add modifiers to the 'A' key shortcut so the key is Shift + A (or Control or Alt).

Version 1.0.9 Released July 13, 2012 21.5 KB Works with Firefox 2.0 and later, SeaMonkey 2.0 and laterImprovements:1. Added support for SeaMonkey web-browser2. Added preference to either append text to file or create a new file

For SeaMonkey 2.11 it's the hidden pref extensions.checkCompatibility.2.11 (it's in about:config, it doesn't exist by default, and you can create it with "Right-click→New→Boolean" with the value false).

For all recent trunk versions (versions ending in a1) it's extensions.checkCompatibility.nightly. For aurora and earlier you must mention the major and minor version numbers (but not any third number) and the letter(s) (but not the digits) if there are any immediately after the minor version.
